We got a hint of this when MTBS saw Palmer at CES 2013, but were sworn to secrecy!

Two feature updates were officially revealed today by the Oculus VR development team. First, in an effort to make the rift more comfortable for people with different types of eyesight, the lens cups are exchangeable:

If you have great vision (or you wear contacts), your vision inside the Rift will match your vision in real life. You'll use eyecup set A.

If you're farsighted, you'll have no vision problems in the Rift because the optics are focused at infinity (which makes your brain think it's looking at something far away). You'll also use set A.

If you're nearsighted, the additional eyecups, B and C, allow you to see inside the Rift as if you were wearing glasses. Again, this is because the lens cups change the focal distance. If you're moderately nearsighted, you'll use set B. If you're very nearsighted, you'll use set C.

For fellow prescription glasses wearers, the gearshift on the side controls how close or far away the screen assembly is from your face, so there is no need to take your glasses off while using The Rift.

Oculus has also completed their testing factory run in Hong Kong, and built 40 complete Oculus Rift "pilot run" developer kits. This pilot run covered everything from the finest manufacturing details, to sensor calibration, to special hardware testing software development. Complete details and walk- through can be found in Oculus' update blog.
